how much water pressure should I have

how much water pressure should I have when i have my motor on muffs?
or should I have any at all?

I hooked the muffs up it take like 10-20second before it starts peeing.

never had it on muffs so i was just wondering.

It's normal. If you have a water pressure gauge, it should read from 2-3 psi at idle up to 10-12 psi at WOT, when on the water.
